T @ZZ whom it may concern:

Be it. known that I, ALYIs .I. IIosKINs, of Edwardsville, in the countyot' Madison and State of Illinois, have invented a certain new anduseful Improvement in Swinging Gates, of which .the following is a full,clear, and eX- act description, reference being had to the accompanyingdrawings, forming part ot' this specification, and in which- Figure .Iis a perspective view ot' the gate in working order. Fig. II is a detailtop view ot' crossbar, showing the rack and pinion that work the gate,and the liiell-cranks, with their connectilig-rods, for operating thelatch. Fig. III is a vertical section taken on line III III, Fig. II,showing the operation ot' the pendent segment -rack and bevel pinion onthe gatepost. Fig. IV is a vertical section taken .on line IV IV, Fig.II, showing a detail of the operating-arms in their pivoted pendentseat, Fig. V is a detail elevation ot' catch with releasing-bardepressed. Fig. Vl is a like view with the releasing-bar raised. Fig,VII is a horizontal section taken on line VIl VII, Fig. V. Fig. VIII isa rear view ot' the catcll-liilate. Fig. IX is a section taken on lineIX IX, Fig. VIII. Fig. X is a detail top view ot' the rear end of gate.Fig. XI is a detail view through the bars of the gate, showin the rearend ofthe catch. Fig. XII a detail view of the bottom of the post; andFig. XIII is a detail section side view of the curvilinear semi-annulus,taken on line XIII XIII, l `ig. IX.

This invention relates to automatic devices for opening, closing, andlatching gates; and the invention consists in features otl novelt)vhereinafter fully described, and pointed out in the claims.

Referring' to the drawings, in which ligures of ,reference indicate likeparts in all the views, l represents the posts ot' the frame, (which maybe planted in the groundg) 2, the

cross-bar of said trame, and C), the braces between the post andcross-bar, to keep the trame from settling out ot' true and thecross-bar from sagging down onto the sluullders of the rotatinggate-post l.

are the longitudinal bars of the main gate C, and 7 are like bars ot'the rearor balance gate,

9 are the braces to the main gate, and 10 the braces to thebalance-gate; il, the toeA bars oi the main gate, and 12 the toe-bars ofthe balance-gate.

The gates are unitedly Carried, and simultaneously swung open and shutby the partial rotaryv movement. of their common post, -Ll. The lowerend ot' said post is bound with a foot-band, and is provided with afoot-pintle, 1i, that works in the socket in the toot-post iti, thatsupports the swinging-gate. The upper end ot the gate-post is seated ina square socket within the clutch-collar IS. Integral with said collarand surmountin g itis the pintle lf), which works in a bearing-socket inthe combined boxing and plate 2l, in which said pintle operates. Theupper end of the pintle 19, which works in the combined box-bearing andplate 2l, that is seated in and on the crossbar 2, carries abevel-pinion, 22, that engages in a segment-rack, 2223, of a segment,23, which hangs pendent from the rock-bar 2l. 25 is a standard on aplate, 26, supporting the central portion ot' the rock-bar. Thejournal-pivots of said bar have their rock-bearings in the vertical armor post 27, that rises t'rom the plate 2l at one end ol' said bar, andin the corresponding post, 28, that ascends from the plate 25J, which isalso secured to the top of the cross-bar and located at the right`distance from the post '3T tor its bearings to acco1n1nodate the pivotat the other end ol the bar.

A segnient-bracket, 30, between the posts 27 and hangs pendent from andis rigidl)v secured to the rock-bar, and is provided with box-brackets3l, in which the operating-levers are seated, and to which theiv aresecured b v the screw-nutted bolts 31 Pendcnt arms 3iare loosel'v hingedto lugsA 35, that are secured near the outer ends to the under side ot'the operatingdevers. These pendent arms are provided with rings 37, thatwork loosely in perforations at the lower ends ot the arms. Pull cordsor chains ft), for operating the automatic latch and swinging device,are fastened to staples all, that are secured beneath the outer ends ofthe levers, pass through rings 37 and hang pendent therefrom, and areprovided with hand-rings that steady the pendent cord and make aconvenient hold in operating the gate.

Hooks 42 on the ends of rods f3 are secured to the perforated lugs leabove the loose ends of the arms 34, and hooks i5 on the farther IOO 1obell-crank lever 54, which is pivoted in the..

lugs 56, that rise from the plate 57, secured on the cross-bar near itsend immediately4 above the latching devices. The upper hook of thependent rod engages in the perforation in the reverse arm ot' thebell-crank lever 54, and the lower end ot the rod connects by its hookwith the bail ($2 of the co-operath'e releasing-bar (i3 oi the latchingdevice. l will now proceed to describe said latching device.

2o (i4 represents the latch, which is hinged on the pin 65, secured tobattens which are attached to the bars of the gate. The forward end ofthe latch rises and falls between the vertical toe-bars of the gate.

G7 represents the bracket-plate that carries the catch and releasingdevices for operating the latch, and is secured to the forward post ofthe frame within which the gate works. A wide slot, GS, is formed in theplate from near 3o its center downward, and a bridge-plate, G9, with adouble incline, projects from its face and forms an elevatoricarriage-way, that guides the latch to its locking-seat. 7 O are pivoteddogs that work on pins 7l. The dog 3 5 on the side the latch approachesis elevated thereby until the latch gains its seat, when it falls andsecures it in its locked position.

The vertical releasing-bar G3, heretofore introduced as hanging pendentfrom the rod 59 4o of the operating device, descends through theperforated cap-plate and works vertically in a box-chamber, 7 3, that isrecessed into the forward post of the frame. The lower end of thereleasing-bar is provided with a projecting lug, 74, and coiled aroundit, near its upper end, within the box-chamber, is a reactionary spiralspring, 75, that pressesagainst the cap 7 2 of the bracket-plate aboveand against the projecting shoulder or pin 7 6 on the releas- 5oing-bar.V The said spiral spring returns the releasing-bar toits normalposition after having released the latch. A stay cord orl chain, 7 7,limits the opening` of the gate to any deired extent, which can be adjusted by len gth ening or shortening the cord. The same purpose may beeffected by a short foot-post, 78, when the cord may be dispensed with.

79 represents a pin that projects from the releasing-bar, and, undercertain contingent 6o circumstances, works, in certain conditions of theoperation, in the semi-annular guideway 8O to remove the projecting lug74 out of the way of the latch, as will be more fully describedhereinafter.

6 5 -The operation of the automatic swinging and latching devices is asfollows: Then the pull-cord 39 on either side of approach is drawn downand released, the pendent arm 34, turning on its pivot, operates therods 43, 50, and 59, in conjunction with the bell-crank 7o levers 47 and54, to elevate the releasing-bar 63, the projecting lug 74 Afrom whichlifts the latch from its locking-seat between t-he pivoted dogs 70.Simultaneously the drawing of the cord lowers the end ot' the lever 32,in 75 conjunction with which it works, and thereby turns thesegment-bracket 30, which operates the rock-bar 24, segment-rack 23, andbevelpinion 22v to swing the gate open, the latch meantime riding up theinclined way formed 8o by the prosirate dog 7 0, after which thereleasing-bar, having e'liected its purpose byn elevating the latchabove the locking-dogs, the spiral spring 75 throws it back ont ot theway ot' the returning latch. Vhen the car- 85 riage, wagon, or otherconveyance has been driven through, the pull-cord pendent 'from theother lever is drawn down and released, when the operation is reversedby the reversal ot the agency. The elevated lever being low- 9o ered,the gate is swung to. The latch on its re* turn running on the inclinedbridge (59 elevates the pivoted locking-dog on the side of its approach,striking again st the end of the other dog, and the one it has justelevated falling behind it, it is against locked in its seat. It is seenthat exactly the same action (the drawing of the cord when repeated onthe same cord or its duplicate on the other side) reopens the gateagain, although the initial draw of roo the cord does not swing the gatepast its lock; but it takes a second duplicate action thereon to obtainthe second responsive result.

The short rear or balance gate, as shown, is

built solid without open spaces between the k bars, so -as to nearerbalance in weight the long open-barred gate, and also balance theresistance to the wind.

Unless some part of the device should at any time get out-of repair, orby accident be 11o arrested in the performance of its work, (acontingency but little likely to occur,) the movement of theco-operating releasing-bar is always vertical; but if through someaccident or in course of time some part should 1 15 get out of repair,so that the projecting lug 74 on the releasing-bar, after lifting thelatch, does not vacate the latch-seat as soon as the pull-cord isreleased, then the action of the advancing latch turns or throws theproj ect 12o ing lug 74 out of its way, the action rotating thereleasing-bar, and at the saine time causing the pin 79, projecting fromsaid bar, to ascend the curvilinear semi-annulus 80, and thus elevatethe releasing-bar, which, after 12 5 the action of the latch, againdrops or is resprung to its normal position, as there is sufcient roomwithin the b0X-chamber 7 3 for the projecting lug to turn aside from thelatch, again descend and regain its position 13o under the latch, ready,when elevated, to again release the same. Then the throw of the latchdislodges said projecting lug from its seat with sufficient force, itmay travel all the Way up the incline of the curvilinear annulus 80, andthen descend through its aeeustonied channel through the vertical slot81,130 regain its normal position under the pressure ot' thereturn-action spring' 7 Otherwise it retraces its steps.

then it is desired to drive through a reaper or other unusually wideload, the Whole Q,ate is easilyv unshipped by lifting ituntil the upperend of the post 4 enters still farther Within the socket l? of theclutcheollar 1S sutiiciently for the pintle at the foot ot' the post tobe lifted from its socket, and the Whole double gate can then be easilyremoved out of the Way, thrmving' the double e'angway into one.

Another advantage of this gate is that it can, when required, be used,independent el vits operating' devices, as a hand-gate, it' any part ot'said devices are temporarily out oit' repair, ior there are no featuresin it that would at any time obstruet its use as a handgate.
